The tubular nut is turned by a handle 2i.

Mounted upon the horiZOntal web ll near its ends and preferably at the central longitudinal axis e; the Web II are upstanding open veshaped jaws 28, which diverge upwardly, and have their apices lowermost and rigidly attached to the web H bywelding or the like. These jaws are prelerably arranged near the ends of the web H to receive and engage the work at remote points, whereby the maximum leverage is obtained for holding the work or handle against lateral displacement.

The body portion IE! is provided at its top and at the apex produced by the horizontal and vertical webs H and I2 with a ring 29 passing through openings 30 and 3|; and this ring 18 passed through an elongated opening 32 formed in a strap 33 having additional openings 34, spaced longitudinally of the strap! When the vise is to be stored away, the strap 33 is adapted to be folded down upon the horizontal web H. The Openings 30 and 3| are in vertical alignment with the opening l l and are at the transverse center ofthe body portion Ill.

Coacting with the upwardly facing V-shaped jaws '23 is an inverted Vr-oshape'd jaw 35, diverging ele ar end havi it apex a ran e uppe m st- A sheu l red it i an d ur e th rear the rod '36 has an extension or hook 37 which i adap ed tehe inser ed i to the l e ed ne ing U352 er a selected opening 34.

the bolt to. placed upon the upper side of the handle, the

passing downwardly through an elongated opening 41, formed in an car 42, rigidly secured to the forward edge of the horizontal web II. The bolt 40 extends downwardly below the ear 42 and passes through washers 43 and engages with a tubular nut 44, having space 45 to receive a lubricant such as grease. This tubular nut is turned by a handle 45. The tubular nut 26 is preferably identical with the tubular nut 45. The invention is not restricted to the arrangement of the rod 35 above the jaw 35 and welded thereto as the hook 3'! and eye 38 could readily be formed integral with the ends of the jaw 35. Various other details of construction can be varied, as is obvious.

The operation of the vise is as follows:

When it is desired to apply the vise to a tree, the rear side of the body portion I is brought next to the tree so that the apices or pointed ends of the jaws I3 will engage the tree. The free end of the chain is passed about the treerand drawn "close to the same and a link of the chain 2I is then inserted within the slot 20 of the inclined portion I9. Should the diameter of the tree be larger than the distance between the points of connection between the chain and the body portion lo, the inclination of the portion I9 will prevent the link slipping out of the slot 20 when the chain is tightened up. The handle 21 is now 7 turned and the tubular nut screwed up upon the .bolt 23, which is drawn forwardly drawing the chain with it and tightening up the same. The opening 24 being horizontally elongated, the bolt 23 can angularly adjust itself in accordance with When the chain 2| is tightened up sufficiently the apices of the jaws will embed themselves in the tree and the body portion will be clamped to the tree so that it will not slip or turn thereon.

If it should be desired to mount the body portion upon a metal plate 41 secured to a truck body or the like, the chain 2|, bolt 23, and tubular nut 26 may be separated from the body portion Ill. Bolts 48 are now passed through the openings I 6 and through openings in the plate 41 and the jaws I3 and I4 clamped to the plate 41 by screwing up 7 nuts as on the bolts 48. This is shown in Figure 4.

In Figure 5, the body portion In is mounted upon a fiat wooden support 50 and the jaws I3 and I4 engage therewith and will sink into the same.

A single bolt may now be employed, passed through the central opening I1, and carrying nut 52. One bolt will be sufilcient under these conditions to suitably clamp the body portion Ill upon the fiat wooden support 50.

The body portion It] being now suitably held I stationary the work will be held disposed within the open upwardly diverging V-shaped jaws 28.

This work may be the handle 53 of a bush-ax which is elliptical in cross-section. This handle may be turned upon, its longitudinal axis so that 1 its maximum radial diameter may be disposed 1 at any desired angle and the handle than clamped in the selected adjusted position. The hook 31 is inserted .into the selected opening 32 or 34 while the tubular nut 44 is screwed down upon The inverted V.-shaped jaw being handle 46 is now turned and the tubular nut 44 will draw the bolt 40 downwardly, which in turn draws the jaw 35 downwardly into clamping engagement with the handle. Since the jaws 28 and These jaws will receive and hold against slipping, work which is elliptical in crosssection, circular in cross-section, or other various shapes in cross-section. Since the jaws 28 are arranged at the ends of the web I I they exert the maximum leverage for holding the handle against lateral displacement when the blade of the ax is being sharpened.

By virtue of the shape of the jaws 28 and 35 they will not injure or scar the handle, which is very important in connection with implements such as a bush-ax.

It is thus apparent that I have provided a portablevise which may be manipulated by a single operator and which will securely hold the work against displacement while it is being worked upon.

This application is a refile in part of my abandoned application for Toolholder and saw clamp, Serial No. 355,492, filed September 5, 1940.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the scope of the subjoined claims.

Having thus described my invention, what I claim is:

1. A portable vise comprising a substantially horizontal elongated body portion, upwardly facing substantially V-shaped jaws mounted upon the body portion near its ends and spaced from each other throughout the major portion of the length of the body portion, a link arranged above the body portion and having a plurality of longitudinally spaced openings formed therein, said body portion having an opening formed therein near one longitudinal edge and generally equidistantly spaced from the V-shaped jaws, said body portion having a second opening formed therein near its opposite longitudinal edge and in substantial transverse alignment with the first named opening of the body portion, a loop mounted within the firstnamed opening of the body portion and freely pivotally mounted within the end opening of the link, said link being foldable down flat upon the upper face of the body portion between the V-shaped jaws, an upper inverted substantially V-shaped jaw arranged between the lower V-shaped jaws and provided at one end with a hook to be readily removably mounted within a selected opening of the link, an eye secured to the opposite end of the upper jaw, a rod having an eye having a permanent loose pivotal connection with the first named eye, the rod extending through the other opening of the body portion and having a loose fit within the opening and projecting below the body portion, the

so that the upper jaw will be in close relation to the upper face of the body portion when the upper jaw is disconnected from the link, a substantially vertical nut arranged beneath the body portion and having screw threaded engagement with the rod, a tube connected with the nut to turn it, and a crank secured to the tube to rotate the tube.
